PATENT SAMUEL KOHN, OF CHICAGO, ILLINOIS.

BICYCLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 585,679, dated J uly6,1897.

Application filed April 26, 1897. Serial No. 633,864. (No model.)

To all whom it may concern:

Beitknown that I, SAMUELKOHN, a citizen of the United States, residinginChicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in .Bicycle-Tires, of which the following'isa specification.

This invention relates'to a fastening which may be employed in lieu ofthe lacing commonly used to close the slit in the casings ofbicycle-tires through which access is had to the air-tube.

My object in the invention has been to-provide a fastening for closingsuch slits which shall be perfectly secure and which can be released inan instant of time and as quickly closed.

The invention consists in the novel devices and in the novelcombinations of parts and devices herein shown and described, andspecified in the claims.

In the drawings forminga part of this specification, and in whichsimilar letters of reference indicate like parts in all the figures,Figure 1 is a plan view of that portion of the tire which is usuallyslit and with my fastening applied. Fig. 2 is a cross-section on theline 2 2 of Fig. 1, and Fig. 3 is a detail showin g the operating andlocking lever.

In said drawings, A represents the casing, and B the inner opening orslit therein, through which the air-tu be is inserted. Along each sideof this opening and preferably riveted to the casing I place strips ofspring metal 0 and D, each provided with guides O and D, respectively,and which may be formed of tongues integral with the strips, if desired.The guides 0 form a slideway in which a sliding bar E may movelongitudinally of the fastening, and the guides D form sockets or loopswhich are adapted to receive and engage the points of the right-angledhooks E, attached to or are integral with said sliding bar and extendingfrom said bar toward the opposite side of the opening. These hooks arepreferably provided in sufficient numbers so that there may be one foreach of the loops D.

It will be apparent from the above description that when the sides ofthe opening are brought together they may be locked simply by moving thesliding bar in such direction as will carry the hooks into engagementwith the guides D", and that to release the fastening it is onlynecessary to move said bar in the opposite direction sufficiently tocarry the hooks out from undersaid guides, neither operation requiringmore than a few seconds of time.

In order to operate the slide, I provide a lever F and pivot it to theend of the strip 0 by a pivot F. Said lever is provided with aneccentric slot F through which passes a stud F upon the sliding bar. Theend of the lever sets under one of the guides 0 when in the closedposition, and in the closed position the lever locks the bar against anymovement whatever. If this lever is turned so as to carry its free endoutward, it will force thesliding bar in the direction which willrelease the hooks, and if swung back into the position shown in thedrawings it will slide the bar in the direction needed to cause thelocking action by the hooks. The pivot F of this lever is passed throughthe strip D, and the opening in said strip is enlarged, as shown at F,in order that the two metal strips may be wholly separated after thefastening is unlocked and thus give ample opportunity for the insertionor removal of the air-tube.

The strips and the sliding bar are all made of thin spring metal, sothat they may readily conform to the rim of the Wheel, and the entiredevice is flat and does not fill up the hollow of the rim nor lift thetire out of it, being as unobjectionable in this regard as the ordinarylacing. I prefer to use a rivet at each of the guides O and D, as shown.

My device is equal in efficiency to the ordinary lacing, and it enablesthe opening and closing of the tire in a fraction of the time requiredby the lacing and with much less trouble.

It will be noticed that the guides (3 and D are separated from eachother, so that they do not interfere with the fleXure of the metalstrips to which they are attached, the open spaces between the guidesbeing formed of a single thickness of metal and being preferablyconsiderably longer in a direction longitudinal of the fastening thanare the guides.

I claim- 1. The combination with the tire-casing of metallic guides atone side of the slit therein,

, seams and a sliding bar moving in said guides and provided With hooksengaging interlocking devices at the other side thereof, substantiallyas specified.

2. The combination With a tireeasing of metallic strips at each side ofthe slit therein, both provided with guides, and a sliding bar held inposition by the guides on one strip, and provided With hooks engagingthe guides upon the other strip, substantially as specified.

3. The combination With a tirecasing of a sliding bar at one side of theslit therein, means for holding and guiding said bar, and loops orengaging devices at the other side of said slit adapted to interlockwith hooks carried by said bar, substantially as specified.

4. The combination With the tire-casing, of

the sliding bar having hooks, essentially as described, and devices forinterlocking With said hooks, and means for sliding said bar,substantially as described.

5. The combination with the tire-casing, of the sliding bar havinghooks, essentially as described, and devices for interloekingwith saidhooks, and means for sliding andlocking said bar, substantially asdescribed.

6. The combination With the tire-casing, of the sliding bar havinghooks, essentially as described, and devices for interlocking With saidhooks, and a swinging lever F having an eccentric slot, substantially asspecified.
